A Guide to Sampling Freshwater Mussel Populations available in PDF, EPUB and Kindle. The objective of this guide is to help field biologists conduct better surveys of freshwater mussel populations. It opens with a discussion of several considerations and a question that should direct the design of any study of mussel populations. The authors then present sampling designs and methods that may be useful to mussel biologists. The also discuss examples of study designs that address several common objectives of studies of mussel populations.

Freshwater mussels continue to be one of the most imperiled groups of animals in North America. Management actions for many mussel species today are critical and might have lasting impacts on preventing local, regional, and perhaps even global extinctions. Citizen scientists can play an important role in gathering field data for informed conservation strategies, which are more important today than ever before. This project aims to develop an inexpensive sampling protocol for freshwater mussels that is teachable and effective for engaging citizen scientists. We developed and tested a rapid assessment survey design based on 10 m x 1 m transects. Results describe mussel community structure and microhabitat associations at 32 sites within five watersheds of the Green Bay Hydrological Basin in northeastern Wisconsin, USA. To gauge the effectiveness of the rapid assessment design, we re-surveyed six productive sites, two within the Oconto River, Pensaukee River, and Duck Creek, using the more intensive Wisconsin Department of Natural Resources (WDNR) standard sampling protocol. This method evaluates mussels in 5 m x 5 m grids sub-sampled in smaller 0.25 m x 0.25 m quadrats. Habitat variables were measured at each transect and grid area to explore the effects of watershed and habitat-level factors on the presence of freshwater mussels. Overall, 4,205 records from 20 mussel species were recorded. Observed richness and abundance varied significantly among these sites; highest numbers of mussels were recorded at the Oconto River, whereas no living mussels were present at any sites within the Little Suamico River. The average time among all watersheds to conduct individual surveys was significantly faster (P

Freshwater mussels are one of the most imperiled groups of animals in North America. Effective conservation strategies and resource management of freshwater mussels require adequately characterizing local mussel assemblages. However, sampling protocols for mussel surveys, including sampling efforts, have not been well established and tested. Furthermore, the percentage of all species captured with a standard sampling effort (e.g., search of man-hours) may vary greatly among sites, introducing biases into our understanding of species-diversity patterns and temporal trends. In addressing both questions, I focused on time-based search, one commonly used sampling technique in stream mussel surveys in the present study. I sampled 18 wadeable-stream sites mainly in east-central Illinois, selected based on watershed size, dominant-substrate type, and historic species diversity. With 16 man-hour search per site, my sampling crew collected 27-942 individuals and 5-18 species per site. I estimated the total species richness at a site with Chao-1 method that accounted for imperfect species detectability. I measured sampling adequacy at a given effort as the % of all estimated species recorded. A frequently used effort, 4 man-hour search, captured 15-100% of all species with an average of 61%. Observed species richness was not significantly correlated with the estimated total richness until sampling effort reached 8 man-hours (Pearson0́9s r = 0.59, p
